Note) H of FRC means the voltage of 1.5V or more while L means the voltage of 1.0V or less. (At VCC = 5V)
Note) For the Hall input, the input H means the condition in which (+) relative to each phase input (-) is higher by 0.1V.
The input L means the condition in which (+) relative to (-) is lower by 0.1V or more.

Caution: For the VCRF voltage of control characteristics, the peak value is to be measured.
Cautions for use)
• When the direct reversion brake is to be used, keep the voltage at the CILIM terminal 3.1V or less so that IOMAX is
not exceeded.
• The capacitor to be used between power supply and GND should be an electrolytic capacitor of 47μF or more.
